Fast rotating neutron stars with realistic nuclear matter equation of state
We construct equilibrium configurations of uniformly rotating neutron stars for selected
relativistic mean-field nuclear matter equations of state (EOS). We compute, in particular, the …

Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts
There is increasing observational evidence that short and long Gamma-ray bursts (GRBs)
originate in different subclasses, each one with specific energy release, spectra, duration …

The Quest for New Correlations in the Realm of the Gamma-Ray Burst—Supernova Connection
Gamma-ray bursts (GRBs) are very energetic cosmological transients. Long GRBs are
usually associated with Type Ib/c supernovae (SNe), and we refer to them as GRB-SNe …

Fast ejecta as a potential way to distinguish black holes from neutron stars in high-mass gravitational-wave events
High-mass gravitational-wave events in the neutron-star mass range, such as GW190425,
have recently started to be detected by the LIGO/Virgo detectors. If the masses of the two …

Early X-ray flares in GRBs
We analyze the early X-ray flares in the GRB" flare–plateau–afterglow"(FPA) phase
observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the …

The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs
We recall evidence that long gamma-ray bursts (GRBs) have binary progenitors and give
new examples. Binary-driven hypernovae (BdHNe) consist of a carbon–oxygen core …
